CVE-2026-104855 is a race condition vulnerability in the Wasmtime WebAssembly runtime affecting versions from 46.0.0 up to but not including 46.0.2 and from 47.0.0 up to but not including 47.0.3. The issue arises from improper synchronization during bulk operations like memory.copy, table.grow, and array.copy, which can expose invalid intermediate states when callbacks mutate or continue using a Store after cancellation or traps. This can lead to crashes, invalid memory access, or garbage collector heap corruption. Embeddings that only access host data or discard the Store after timeout are not affected. The vulnerability has a low CVSS score and is fixed in versions 46.0.2 and 47.0.3. Join the discussion | GCVE Database | 10/02/2026, 17:37:50 UTC Added: 10/02/2026, 19:59:37 UTC |
